> h3. *Motivation*
> After Catalog was introduced and recovery for Distribution zone manager was completed, it is needed to reimplement {{CausalityDataNodesEngine#dataNodes}} according to the new circumstances. Most of the code from this method must be removed, and entities from the catalog must be reused.
> h3. *Definition of done*
> {{CausalityDataNodesEngine#dataNodes}} is reimplemented according to the new circumstances.
> h3. *Implementation notes*
> Seems that we can remove {{CausalityDataNodesEngine#zonesVersionedCfg}} could be removed and Catalog must be used, also we don't need logic for {{CausalityDataNodesEngine#getLastConfigRevision}} because it is guaranteed that immediate scale Up/Down intents will be handled in the corresponding handler
